Hi I am using interaction expansion to solve a lattice problem using DMFT. I want to find the dynamic density-density correlators as well. How can it be done within interaction expansion scheme. While the same can be done turning the corresponding flag on for hybridization-expansion scheme, and I have used it vigorously.
